The study, conducted by a team of researchers from the National Institutes of Health (NIH), was published today in the Journal of Allergy and Clinical Immunology.
The study, which included 3,000 women and 1,000 men ages 45 to 69, found that about a third of the women tested had reported having allergic reactions to cosmetics, compared to around 20% of the men.
In fact, the researchers say that most of the allergy reports they found were from women.
The researchers analyzed data from 1,058 women and 2,854 men from a national sample of women over age 65.
The women and men were asked about their daily exposure to cosmetics and what products they use, including whether they had used any of the ingredients tested, and whether they felt an allergic reaction to them.
The participants also were asked what their favorite brands of cosmetics they use.
The researchers found that the most common allergic reactions they found in women were a sensitivity to products with fragrance, and skin irritation.
The majority of people with allergies to fragrance-containing products were men, the study found.
For women, the allergic reactions were more likely to be reported when the products were fragrance-free, as compared to products that had fragrance in them.
However, the people who reported allergies to products containing fragrance had higher rates of other allergic reactions, including eczema and a sensitivity of the skin to aldehydes.
The ASCS study found that those who had been exposed to fragrance were twice as likely to have an allergic response to products made from animal byproducts, compared with women who had not been exposed.
The results are in line with previous research that has shown a link between cosmetics and skin allergies.
